> In the first trimester, choline plays a vital, often-overlooked role in supporting your baby's neural tube development and laying the foundation for cognitive function.

During the foundational weeks of your first trimester, while your body is busy creating the very blueprint of a new life, certain nutrients become incredibly important. Choline, a nutrient often grouped with B vitamins, is one of these unsung heroes, working alongside folate to support crucial neural tube development and the early formation of your baby's brain, particularly the hippocampus, which is essential for memory.

It's a surprising reality that over 90% of US pregnancies don't meet the recommended choline intake, a fact highlighted by ACOG in 2017. This under-recognition means many expectant parents might not be aware of its significance, especially when most prenatal vitamins contain very little, if any, choline. Understanding this gap can bring a sense of clarity and empower you to make informed decisions about your nutritional support during this delicate time. Just as we consider nutrients like [Iodine in the first trimester](/nutrition/iodine-trimester-1) for thyroid function and brain development, or [Calcium in the first trimester](/nutrition/calcium-trimester-1) for early skeletal formation, choline deserves a place in your focus.

Prioritizing food sources is a wonderful, gentle way to ensure you're getting enough choline. Eggs, particularly the yolks, are a fantastic source, offering around 150 mg per egg. This is why diets that focus solely on egg whites might miss out on this key nutrient. Beyond eggs, incorporating foods like beef, salmon, chickpeas, and soybeans can contribute to your daily intake. For those following vegetarian or vegan eating patterns, careful planning or a thoughtful conversation with your care provider about supplementation might be a helpful step to ensure adequate levels.

Research continues to underscore choline's long-term impact. Studies, such as those published in the American Journal of Clinical Nutrition, have linked a mother's choline intake during pregnancy to her child's cognitive performance later in life, even at age seven. This evidence reinforces the idea that the nutritional choices you make now are building blocks for your child's future. As your pregnancy progresses, your nutrient needs will continue to evolve, much like the ongoing support for bone health discussed in [Calcium in the second trimester](/nutrition/calcium-trimester-2).

Navigating all the information about pregnancy nutrition can feel overwhelming, but it doesn't have to be. My goal at Pregnancy Power Hour is to offer calm, evidence-based guidance, helping you feel clear and confident in your choices. Remember, your care provider is your best resource for your specific situation and any medical advice.
